hey guys, i have been racing a bit these days, mostly with my friends 335i, and 535i. ive noticed that when my vdc is off, i get a lot of wheel spin, and the car takes some time to get off the line. my friend has to short shift in order to not blow me off, lol. i know i have sucky tires, and i also get my timing advanced. what are some things i could do to get better performance off the line?

 

take it to the track

 

buy better gripping tires and race on the track only where tractions are better.

 

in reality, practice, practice practice. takes a while. It used to be a pain in the butt to launch my 07 subbie. Wider tires, grippier tires will help some, but most of it is still practice.

 

yea i figured practice will help a lot, and wider tires.

 

turn you vdc on.

 

Are you auto or stick. If you are auto, does your car have the sport package. If you have auto, and no sport package, you do not have a lsd so only one wheel is spinning on launch.

 

i am auto, and dont have sport package

 

yea i would, but my car wont be performing 100%

 

Tires and a LSD.

 

hmm how much do lsd's run for our cars? i heard the nismo lsd is pretty decent

 

+1 - need LSD... it used to drive me nuts until I got Quaife.

 

It's either your tires, the surface, or both. It has absolutely nothing to do with the fact that you don't have an LSD. An LSD WILL NOT improve off the line traction. My 03 sedan with the sport package does not have LSD and it has absolutely no problems lighting up the 17s in two perfectly uniform lines.

 

Keep your VDC on. If you're spinning the tires, you're not performing 100% either.

TAKE IT TO THE TRACK.

There are cars much faster than yours that keep the VDC on for straight line pulls. Learn from them

 

If the weight distribution is even, there is usually no problem lighting up both tires with an open differential. It's been done many times.

The OP's biggest problem is tires. What's more than likely happening is that he's spinning up the right inside tire and just sitting there baking it to kingdom come. If he had a set of stickier rubber, he would probably launch better and come out with little wheel spin.

He could also learn to feather the gas pedal off the line and not hit it so hard.

An LSD does help with launching if you have good tires. If one of the tires breaks traction, the other one still pushes and does help in allowing the other tire to regain traction rather going into a "1 tire fire" situation.
